Hi, Can somebody please make the dialog for closing a window with tabs open? -- Cheers Jorge.-

FLTK2 has a bug in that it regards the first menu item letter as a shortcut. Note: I tried with invisible shortcuts doing nothing, removing shortcuts and all that stuff, until I found this way to workaround the problem. Note2: Alt-W and Alt-X are accelerators, so they're OK. AFAIS there's no more segfault here. -- Cheers Jorge.-

I usually add my own debugging statements rather than use DEBUG_MSG . Maybe that says more about my ego than anything else :-) but FWIW I wouldn't miss DEBUG_MSG either. Regards, Jeremy Henty

It seems that carrying around widget, link and html->visited_color could do the trick. Maybe it's not worth the effort as the new window is enough visual feedback, and also the new tab...

We could leave the link alone and change the mouse cursor instead. The link not changing color when openning it with the menu is IMO a bug, I'm looking for... BTW, the linear search patch is much simpler and as link clicking is not a performance critical task it could be left implemented in O(n). -- Cheers Jorge.-

Just think about: <html> <body> <a href="http://slashdot.org">slash<b>dot</b></a> </body> </html> After clicking, the dot is no longer bold. Cheers, Johannes

It is assuming that link numbers are always increasing, right? Can we assume this in dw/*? src/html.cc seems to be implemented currently in way that this is true. But perhaps we could/should reuse link numbers for equal destination urls in the future? Or someone might just choose hashes of the url string as link number. BTW. with both implementations I now see issues with this example: <html> <body> <a href="http://www.dillo.org">dillo</a> <a href="http://slashdot.org">slashdot</a> <a href="http://www.dillo.org">dillo</a> </body> </html> When opening the first link in a new window, it doesn't change color in the original one. When opening it in a tab, the first one changes color. After a reload also the second one changes color. Am I missing something? Cheers, Johannes

I'm on page A. I try to go to page B, which seems to be taking a long time to think about resolving or contacting the host or whatever. I hit stop and go back to reading and want to continue loading images. Or if DNS couldn't resolve the hostname, I could hit stop to re-enable loading images.

What's the idea behind it? If you want to get rid of empty cache entries from unsuccesful http connections, it's more complex than that. BTW, I plan to do that after the release. > PS Stop should have a keyboard shortcut, I think. > I long had a reflex of hitting ESC from the netscape/mozilla > days, but of course ESC would be inconsistent for dillo. Could be. Maybe Ctrl-P. Although Stop is not yet doing exactly what it should. -- Cheers Jorge.-
